Modern electric power systems of Japan are characterized by high density, wide area coverage, and a complicated structure. Multimode oscillations occur in the generators connected to the systems. These oscillations represent a combination of high‐ and low‐frequency modes that occur between individual power systems and oscillations of other types, such as the SSR and cross‐compound machine oscillations, which are characteristic mode oscillations of generators. In this paper, we first construct a real model of the generator that realizes the multimode oscillations. Next, model reduction of this real model is carried out, and a design model to be used for the control design is constructed. The H ∞ control design based on the modern control theory is presented by using this design model, which implements the damping of power system oscillations and robust stabilization of other multiple modes. In conclusion, we confirm that the target parameters of the control design have been achieved. © 2004 Wiley Periodicals, Inc.
